Red copper oxide supplies CuO. A colorant and flux; reduced form of black copper oxide (CuO). Red copper oxide is usually coated with some material to prevent reoxidation, and because of this does not mix well into water. Try washing it with alcohol to remove the coating. Red copper oxide is often used for copper fuming in pit/sagger firing.
